Rules of word formation

1) Coinage: creation of new words such as names of products. Example: Kleenex (to refer to tissue paper). Kleenex is the brand name to refer tothis product. Other examples are: Xerox and Kodak, which are brand names used to name the product they refer to in English.

In Chile we usually say Confort to refer to any type of toilettepaper. We know that Confort is a brand of a particular toilette paper produced in Chile, but we also have other brands of toilette paper such as Favorita, Suave, Preferido, etc.
